How can yall identify love bombing

Okay so like I never rlly understood this, maybe it's cus of my previous relationship but I suck at showing affection and care for ppl so i tell them instead of how much they're like dear and stuff to and since they often mean alot to me, it's an essay but anyways I learned that with my ex. They would often tell their friends how much he loves them and stuff and it seems wholesome but maybe it's manipulative
somewhat- to me personally idk abt his friends. Due to that thing, I feel guilty when I get mad at them and I still do.

Someone told me that what I'm doing could be considered a "love bomb" and that it's awful so like now im confused on how else can I show affection like towards a friends and not necessarily a lover...
